Examination of specimens and relevant literature and field investigation reveal that Actinodaphne sessilifructa is a representative of Litsea rather than Actinodaphne. A new combination, Litsea sessilifructa, is proposed.

Lindera, a core genus of the Lauraceae family, has important economic uses in eastern Asia and North America. However, its historical diversification has not been clarified. In this study, we report nine newly sequenced Lindera plastomes. The plastomes of these nine Lindera species range from 152,211 (L. nacusua) to 152,968 bp (L. metcalfiana) in length, similar to that of another Lauraceae species, Litsea glutinosa (152,618 bp). The length variation of these plastomes derived from the length variation in the loci ycf1, ycf2, \ψycf1, and ndhF-\ψycf1. Comparing our sequences with other available plastomes in the Lauraceae indicated that eight hypervariable loci, ihbA-trnG, ndhA, ndhF-rpl32, petA-psbJ, psbK-psbI, rps16, trnS-trnG, and ycf1, could serve as DNA barcodes for species delineation, and that the inverted repeats (IRs) showed contraction/expansion. Further phylogenetic analyses were performed using 32 complete plastomes of Lauraceae and seven barcodes from 14 additional species of Lindera and related species in the core Lauraceae. The results showed that these Lindera species grouped into two or four sub-clades, and that two Litsea species and Laurus nobilis were located in the same sub-clade as five Lindera species. These data support a close relationship between the genera Laurus, Lindera, and Litsea, and suggest that Lindera is polyphyletic.

O Parque Estadual das Laur\áceas \é o maior parque estadual no Paran\á, sul do Brasil. Localiza-se nos munic\ípios de Adrian\ópolis, Bocai\úva do Sul e Tunas do Paran\á, em uma \área montanhosa do Primeiro Planalto Paranaense, conhecida como Serra do A\çungui, a qual faz parte da bacia do rio Ribeira. O parque \é quase que totalmente coberto pela Floresta Ombr\ófila Densa e, como seu nome sugere, tem consider\ável presen\ça de \árvores da fam\ília Lauraceae. Apesar disso, faltava informa\ç\ão detalhada sobre esse grupo de plantas na \área. O objetivo principal desse trabalho \é gerar conhecimento sobre suas esp\écies, reunindo informa\ç\ões que possam auxiliar a gest\ão dessa unidade de conserva\ç\ão. No primeiro cap\ítulo n\ós apresentamos o tratamento taxon\ômico das esp\écies que ocorrem no parque e em sua zona de amortecimento. Foi elaborada chave de identifica\ç\ão, descri\ç\ões, dados sobre distribui\ç\ão geogr\áfica e fenologia, pranchas fotogr\áficas, al\ém de coment\ários que auxiliam a identifica\ç\ão de cada uma delas. Constatamos a exist\ência de 51 esp\écies distribu\ídas em dez g\êneros, o que representa a maior riqueza de esp\écies j\á registrada por um estudo taxon\ômico regionalizado para a fam\ília no sul do Brasil. No segundo cap\ítulo n\ós analisamos uma comunidade de Lauraceae dominante em um remanescente muito bem conservado dentro do parque, buscando descrever sua estrutura, e com isso, resgatar a discuss\ão sobre os est\ágios sucessionais das florestas sul brasileiras atrav\és da sua compara\ç\ão com diversos par\âmetros. Para isso, realizamos uma amostragem fitossociol\ógica de dois hectares de floresta. Constatamos que a fam\ília \é capaz de se organizar em uma comunidade complexa inserida na matriz florestal, com v\ários estratos, v\árias idades e v\árias esp\écies, com caracter\ísticas de est\ágio cl\ímax. Conclu\ímos tamb\ém que o parque possui uma associa\ç\ão vegetal tipo Ocotietum, que \é uma tend\ência para os est\ágios sucessionais mais desenvolvidos da Floresta Ombr\ófila Densa Montana subtropical. No terceiro cap\ítulo n\ós revisamos a distribui\ç\ão geogr\áfica das esp\écies que foram identificadas no parque, buscando compreender essa comunidade no contexto brasileiro, em especial no Bioma Mata Atl\ântica. Para isso, realizamos an\álises de similaridade flor\ística com outras 46 comunidades no bioma e tamb\ém an\álises de esp\écies indicadoras. Constatamos a forma\ç\ão de sete grupos flor\ísticos. A comunidade do parque ficou agrupada com outras quinze, todas situadas na regi\ão montanhosa ao longo da costa Atl\ântica, entre os estados do Rio de Janeiro e Santa Catarina. Esse grupo flor\ístico de Lauraceae \é aqui denominado como \“Serra do Mar\”, para o qual foram selecionadas 17 esp\écies indicadoras.

The Laur\áceas State Park is the largest state park in Paran\á, southern Brazil. It is located in the municipalities of Adrian\ópolis, Bocai\úva do Sul, and Tunas do Paran\á, on a mountainous area of Paran\á\’s First Plateau (Primeiro Planalto Paranaense) known as A\çungui mountain range, which is part of the Ribeira river basin. The park is nearly entirely covered by Atlantic Rainforest and, as its name suggests, it has a large presence of trees of the Lauraceae family. Nevertheless, detailed information about this group of plants in the area was lacking. The main goal of the present paper is to generate knowledge about its species, gathering information that may be helpful on the management of this conservation unit. In the first chapter we present the taxonomic treatment of the species that occur in the park and in its buffer zone. Identification keys, descriptions, data on geographic distribution and phenology, and photographic plates are provided, as well as comments that help to identify each species. We found 51 species distributed in ten genera, which represent the greatest species richness recorded by a regionalized taxonomic study for the family in southern Brazil. In the second chapter we analyzed a dominant community of Lauraceae in a very well preserved remnant within the park, aiming to describe its structure, and with this, we bring up the discussion about the succession stages of the Brazilian forests through the comparison of several parameters. For this, we performed a phytosociological sampling of two hectares of forest. We verified that the family is able to organize itself in a complex community inserted in the forest matrix, with several strata, several ages and several species, with characteristics of climax stage. We conclude also that the park has an Ocotietum type of vegetation, which is a tendency for the most developed successional stages of the subtropical Montane Atlantic Rainforest. In the third chapter we review the geographic distribution of the species that were identified in the park, searching to understand this community in the Brazilian context, especially in the Atlantic Forest Biome. For this, we performed analyses of floristic similarity including other 46 communities from the same biome, and also analyses of indicator species. Seven floristic groups were recovered. The park community was grouped with fifteen others, all located in the mountainous region along the Atlantic Ocean, between the states of Rio de Janeiro and Santa Catarina. This particular floristic group of Lauraceae is here named \"Serra do Mar\", for which 17 indicator species were selected.

Epidermal characters are widely used in identification of fossil plant material, yet they are insufficiently known in many extant taxa. Here, we examined the cuticle and stomatal complex in 85 species of the Ocotea complex by optical and scanning electron microscopy. We defined 19 types of stomatal surface appearance, which were mostly consistent with genera or species groups recognized based on reproductive characteristics. The epidermal features support the conclusion derived from DNA analyses that Ocotea is heterogeneous in its current circumscription. We suggest an evolution of the subsidiary cells in the Ocotea complex species from asymmetric to symmetric, and from relatively wide to narrower shapes of the stomatal complex.
